					<p>HTMLInfo is used to show and hide custom HTML page elements, such as a context menu, tooltip, or text editor made of HTML.</p>
					<p>Properties that can be set to an HTMLInfo include:</p>
					<ul>
						<li><a href="TextEditingTool.html#defaultTextEditor">TextEditingTool.defaultTextEditor</a></li>
						<li><a href="TextBlock.html#textEditor">TextBlock.textEditor</a></li>
						<li><a href="GraphObject.html#contextMenu">GraphObject.contextMenu</a></li>
						<li><a href="Diagram.html#contextMenu">Diagram.contextMenu</a></li>
						<li><a href="GraphObject.html#toolTip">GraphObject.toolTip</a></li>
						<li><a href="Diagram.html#toolTip">Diagram.toolTip</a></li>
					</ul>
					<p>When a context menu is set to an instance of HTMLInfo,
						<a href="ContextMenuTool.html#showContextMenu">ContextMenuTool.showContextMenu</a> and <a href="ContextMenuTool.html#hideContextMenu">ContextMenuTool.hideContextMenu</a>
						call <a href="HTMLInfo.html#show">show</a> and <a href="HTMLInfo.html#hide">hide</a> respectively. You may define <a href="HTMLInfo.html#mainElement">mainElement</a>
					instead of <a href="HTMLInfo.html#hide">hide</a> in order to automatically use a default hide method.</p>
					<p>When a tooltip is set to an instance of HTMLInfo,
						<a href="ToolManager.html#showToolTip">ToolManager.showToolTip</a> and <a href="ToolManager.html#hideToolTip">ToolManager.hideToolTip</a>
					call <a href="HTMLInfo.html#show">show</a> and <a href="HTMLInfo.html#hide">hide</a> respectively.</p>
					<p>When a text editor is set to an instance of HTMLInfo,
					<a href="TextEditingTool.html#doActivate">TextEditingTool.doActivate</a> calls <a href="HTMLInfo.html#show">show</a> and <a href="TextEditingTool.html#doDeactivate">TextEditingTool.doDeactivate</a> calls <a href="HTMLInfo.html#hide">hide</a>.</p>
					<p>For HTMLInfo to work, you must define <a href="HTMLInfo.html#show">show</a>
						and either <a href="HTMLInfo.html#hide">hide</a> or <a href="HTMLInfo.html#mainElement">mainElement</a>.
						Typical usage will also stop the <a href="ContextMenuTool.html">ContextMenuTool</a> once the desired context action occurs,
					typically by calling <code>diagram.currentTool.stopTool();</code>.</p>
					<p>Example usage of HTMLInfo can be found in the
						<a href="../../samples/customContextMenu.html">Custom Context Menu</a> and
						<a href="../../samples/htmlLightBoxContextMenu.html">HTML LightBox Context Menu</a> samples, the
						<a href="../../samples/customTextEditingTool.html">Custom TextEditingTool sample</a>, and the
